It's about helping you to save
money and to do your
part in saving the environment and preserving the world's natural
resources for future generations. There are many little things we
can do in our everyday lives to this end, but here we will show you a fun
weekend project that will make a lasting impact with very little ongoing
effort or cost. Specifically, the domestic Greywater Recycling
System, shown below.

First, some definitions...

"Green" has become
the symbolic color of the ecology movement and environmentalism.
It is also used to represent an
object's properties or a person's beliefs or actions as they relate to
preserving the
environment.

"Grey" refers to "greywater"
-- our domestic wastewater that results from
bathing and washing laundry. Greywater is cloudy in appearance,
in contrast to clear fresh water and heavily contaminated "blackwater".

Why recycle "greywater"?

Once fresh, potable water has
become greywater, it is a free resource. You've already
paid for it the first time; therefore, the collection
and reuse of this greywater will not cost you or the environment any
more than its initial use. This results in a significant water
savings for your home, a reduction of your carbon footprint, and a cost
savings to you, as well. We'll look at all of these benefits in
more detail later.

But what can I use my discarded greywater for???

Greywater, obviously, cannot take the
place of potable water throughout your home. But there is one
glaringly obvious application where the luxury and expense of potable water is not
needed -- in fact, it seems absolutely absurd to process and purify water for this
purpose. And this application is... you guessed it... flushing
your toilets.This is not the only possible
use. Indeed, there are many systems and plans on the market today
for applications that use greywater to irrigate a lawn or garden.
But since the outdoor use of greywater is sometimes seen as a potential
public health risk, it is typically heavily regulated and requires the
piping of greywater out into large underground leach fields. Such
systems require extensive digging, piping, and landscaping, and still they do not
reduce water consumption -- they only save on
the costs of treating the greywater at the sewage plant.
With our plans, your homebrew Greywater
Recycling System will collect, filter, and store household greywater and then
pump
it back out, on demand, for flushing your home's toilets. It will actually
reduce your household's monthly water consumption in addition to
decreasing the load on purification and waste treatment
facilities. And since it will be completely contained within your
private home, you should be able to build and install your system
yourself without the hassles of government
regulations.
